University of Texas at Austin study measuring methane emissions released from natural gas production

Green Car Congress

NOVEMBER 5, 2012

A research team led by The University of Texas at Austin, and including engineering and environmental testing firms URS and Aerodyne Research, is conducting a major field study to measure methane emissions from natural gas production, about which little empirical data exist.

The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.

AUGUST 12, 2016

The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

SEPTEMBER 7, 2009

By including upstream emissions from fuels, GHG emissions from cities exceed those attributed to direct end-use by up to 24% (for Toronto). By including upstream emissions from fuels, the researchers found that GHG emissions attributable to cities exceed those from direct end use by up to 24%. Tonnes CO 2 e/capita.

These observations may also assist air quality managers in assessing the most effective approaches to emission reduction programs that will improve air quality. If emissions of that molecule are reduced, then ozone formation will be reduced—critical information for air quality managers.

We are beginning to get a sense of regional variation in methane emissions from natural gas production. CIRES is a partnership of NOAA and the University of Colorado Boulder. In the new study, the researchers also reported their findings by region: Methane emissions in the Marcellus region of northeastern Pennsylvania were about 16.5

The global economic recession of 2008—which severely depressed light-duty vehicle sales—resulted in an increase in the age of the light-duty vehicle fleet in the US that likely slowed the rate of decrease of fleet average emissions, according to a study by Gary Bishop and Donald Stedman at the University of Denver.

JULY 18, 2010

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. VOC emissions would have been reduced by 57 tpd.

Instead, the research team found that ammonia emissions from cities are much larger than recognized, occur at the very times when unhealthy particulate matter is at its worst, and when agricultural emissions are at daily or seasonal lows. Vehicle NH 3 emissions depend on road grade, driving mode, and vehicle age.
